The 22-year-old posted a final round of 69 to wrap up an eight-shot success with a record low score for the tournament of 16 under par.
The achievement is all the more remarkable given the manner in which the Holywood player failed to hold on to a four-shot lead on the final day of the Masters at Augusta just two months ago, eventually finishing 10 strokes adrift of winner Charl Schwartzel.
